Struct supercow::ext::InlineStorage

pub struct InlineStorage<A, B>(_);

Causes the OWNED or SHARED value of a Supercow to be stored inline.

This makes allocation of owned Supercows much faster, at the expense of making the Supercow itself much bigger (since it now must contain the whole object).

Trait Implementations

impl<A: Clone, B: Clone> Clone for InlineStorage<A, B>

fn clone(&self) -> InlineStorage<A, B>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<A: Copy, B: Copy> Copy for InlineStorage<A, B>

impl<A: Debug, B: Debug> Debug for InlineStorage<A, B>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<A, B> Default for InlineStorage<A, B>

fn default() -> Self

Returns the "default value" for a type.

impl<A, B> OwnedStorage<A, B> for InlineStorage<A, B>

fn allocate_a(&mut self, value: A) -> *mut ()

Allocates the given owned value.

fn allocate_b(&mut self, value: B) -> *mut ()

See allocate_a.

unsafe fn get_ptr_a<'a>(&'a self, _: *mut ()) -> &'a A

Extracts the immutable reference from the saved pointer and storage.

unsafe fn get_ptr_b<'a>(&'a self, _: *mut ()) -> &'a B

See get_ptr_a.

unsafe fn get_mut_a<'a>(&'a mut self, _: *mut ()) -> &'a mut A

Extracts the mutable reference from the saved pointer and storage.

unsafe fn get_mut_b<'a>(&'a mut self, _: *mut ()) -> &'a mut B

See get_mut_a.

unsafe fn deallocate_a(&mut self, _: *mut ())

Releases any allocations that would not be released by Stored being dropped.

unsafe fn deallocate_b(&mut self, _: *mut ())

See deallocate_b.

unsafe fn deallocate_into_a(&mut self, _: *mut ()) -> A

Like deallocate_a(), but also return the owned value.

unsafe fn deallocate_into_b(&mut self, _: *mut ()) -> B

See deallocate_into_a.

fn is_internal_storage() -> bool

Returns whether this storage implementation ever causes the owned object to be stored internally to the Supercow.
